This video claims that our culture overuses the words "good" and "bad". It also goes so far as to say that these words indicate we may be lying about our true views by not being perhaps more superlative or specific.
Edit: OK I'll try to make this an objective question. Instead of asking what you think about this, I'll ask:
Are there any written arguments that agree or disagree with this opinion in classic english language literature, philosophy, or textbooks? Where could I read more on this topic?
